We're kicking off 2026 with a batch of updates focused on quality visibility, automated error detection, and annotation workflow improvements. Here's what's new for teams working on autonomous vehicle training data.

Quality Alignment Gets More Powerful

Quality Alignment now lets you drill down from aggregated user metrics to individual assignments. This makes it easier to:

• Identify which specific tasks are driving quality trends
• Provide targeted feedback to annotators
• Investigate issues at a granular level

We've also added the ability to search users by email address in the user dropdown.

Where to find it: Team Management → Productivity Insights → Quality Alignment

3D Segmentation Support

Quality Alignment now supports 3D Semantic Segmentation and 3D Instance Segmentation. We're rolling this out across projects—contact your account team if you'd like historical data backfilled.

Quality Estimations for Requests

A new Alignment Analytics view displays quality metrics at the request level, including estimated quality for unreviewed assignments. Use this to make data-driven decisions about sampling rates and review allocation.

Programmatic Checks: Catch More Errors Automatically

We've expanded our programmatic checks to help you catch annotation errors before delivery

Cube3D Scale Ratios

New checks validate the relationship between width, height, and length of 3D cuboids:

• • cube3d_length_to_height_ratio
  • cube3d_length_to_width_ratio
  • cube3d_width_to_height_ratio

For example, you can automatically flag when a vehicle annotation is wider than it is long—something that's almost always an error.

Polygon Area Validation

Check that polygons and multi-polygons fall within expected size ranges:

• • polygon2d_area — minimum/maximum area in pixels²
  • multipolygon2d_area — for multi-polygon annotations

Scene Property Checks

Validate scene-level properties like weather and lighting conditions:

properties_str.weather = "rainy"
properties_str.weather ALL IN ("rainy", "sunny")

Per-Camera Evaluation

Run checks per camera instead of across all cameras combined—essential for multi-camera setups where an object may be occluded in one view but visible in another.

Annotation Tool Updates

Split Polygon to New Object

Quickly fix cases where multiple objects were incorrectly annotated as one. Right-click any polygon in a multi-polygon and select "Split to new object."

Prevent Editing in Review Tasks

A new request setting restricts reviewers to feedback only, preventing accidental edits during quality review phases.

More Improvements

• Overwrite existing properties
• Remove redundant points with one click
• Lane connection customization
• Project 3D lines to 2D

We'll be at Tech.AD Europe in Berlin, March 23-24. Stop by our booth to see these features in action.
